HOISTING APPARATUS.

To all %kom it may concern Be it known that I, NovALIs LACROIX, a citizen of the United States, residing at Belle Center, in the county of Logan and State of Ohio, have invented certain new and useful Improvements in Hoisting Apparatus, of which the following is a specification, reference being had to the accompanying drawings. v

Ihis invention relates to an improved hoisting apparatus and has for its primary Object to provide manually operable means for hoisting wagon bodies, hay racks and the like, having certain improved structural features whereby the same may be operated with ease and facility.

In its more specific aspect, the present invention provides two pairs of beams mounted upon opposite sides of a suitable frame structure and fulcrumed intermediate of their ends, a drum or windlass rotatably mounted in the frame, and flexible connections detachably engaged therewith and connected to the respective beams, means centrally secured to the windlass for rotating the same, and additional means-for looking the windlass against rotation to retain the beams in various angular positions.

The invention has for a further Object to produce an apparatus of the above character, whereby two bodies may be simultaneously elevated, or one of the bodies raised while the other is lowered, said apparatus being provided with means for anchoring any one of the beams to the frame structure, whereby the body which has been lifted 'thereby may be disposed at an inclination to discharge its contents into a storage bin.

The invention has for an additional Object to provide a hoisting apparatus which is simple and inexpensive in its construction, as well as strong and durable and of great convenience in practical use.

With the above and other objects in view, the invention consists in novel features of construction, combination and arrangement of parts as will. be hereinafter referred to and more particularly pointed out in the specification and claims.

For a full understanding ofthe invention, reference is to be had to the following description and accompanying drawings, in which- Figure 1 is a side elevation of a hoisting apparatus constructed in accordance with the preferred embodiment of my invention;

Fi g. 2 is a top plan view thereof; Fig. 3 is an enlarged elevaton ofthe drum or windlass;

Fig 4 is a section taken on the line 4-4: of

. ners, indicated at 6, \Vhereby the apparatus may'be readily moved from place to place. Upon the upper longitudinal bars 7 of the framestructure and adjacent to each end thereof, a U-shaped clip 8 is secured.

9 designates the beams, each of which is equipped with a loop 10, said loop being engaged in one of the clips 8 and having its ends pivotally secured upon opposite sides of the beam at its center. The upper edge of each of the beams 9 has a longitudinally extending metal strap 11 secured thereon, the ends of which are bent around the ends of the beam and secured to the lower edge thereof, thereby producing the eyes, indicated at 12.

A drum or windlass 13 is provided upon its end with trunnions 14: which are journaled in suitable bearings mounted upon opposite ends of the frame 'structure 5. ends of the drum are reinforced by the flanged sleeves or collars 15. A metal sleeve 16 is'also secured upon the drum 13 centrally thereof, by means of the screws indicated at 17. and in this sleeve the inner ends of the radially disposed spokes of an operating wheel 18 are secured two of them extending in one continuous piece through the drum 13. Pius 19, extend at right angles to each 'other-also through the sleeve 16 and the drum, and project radially from the periphery of the drum. These pins are adapted to be received in an Opening 21, providedin a looking lever 20 which is fulcrumed at one of its ends, as at 9 2, upon the frame structure 5. This pivoted end of the lever is very loose so as to admit of its vertical movement. It will be understood that when the lockin g lever is enga ged with one of the pins 19, the drum or windlass 13 will be held against rotation, 'To each end of the drum The 13 and" in spaced relation longitudinally thereof, the screws or bolts 23 are fixed'in opposite sides of the drum, or othersnitable fiexible elements indicated at 2-l are provided with rings or eyes 25 Upon* one of their ends for detachable engagement with said headed bolts; The other ends of ends of the beams 9.

v beams.

the respective chains are provided with hooks for engagement with the eyes 12 on the inner '25' designates a hay rack which is suspended by means of suitable'chains 26 from the'ends'of the'beams 9 projecting beyond one' side of the'. frame 5. A wagon body,

shown a-t'27, is similarly connected by the wardlyon the opposite side of the drum and are connected to the other bolts 23. It is thus apparent that when the drum is rotated through the medium of the operating' wheel 13 in the direction indicatedby the arrow, the wagon body 27 will be raised or elevated while the rack 25 willbe lowered. After the wagon body and its contents-have been thus lifted to the desired height, the looking lever 20 is engaged with oneof the pins -19 so asto hold the drumagainst reverse rotation. Each' or the beams-Q is further provided upon its inner end with a look 29 for engagement by an eye or ring attached to a short chain or cable indicated at 30. which is secured tothe frame*5. By now anchoring one of the beams 9, the drum may be released and its rotation reversed so that'one end-of the \vagon body- 27 will be lowered, thns d-isposing` the same at a'lon'gitndinal inclinationto etfect'the dischargeof its contents into-the silo--or otherstorage bin.- By providing a detachable connection between the chains 24 and the drum 13, these chans may be so connected'to the drum as to' operate, the two pairs ofbeams in unison and isimultaneously hoist the wagon bodies orother objects suspended from their outer ends. When the 'chains 26 and 28 are unhooked from theirloads which 'they have raised or lowered. the inner ends' of the .beams being slightly heavier than their outer ends, these will move' downwardly, the cha-ins 21 sagging below the druni 13. By the provision of 'the anchor ing means for the'beams and their detachable connection with the drum, said beams may be operated either singly, or in pairs. V l A ln- Fig. 5 of the drawings Ihaveshowna slightly modified construction of the beams 9, wherein the extremities of the metal rein-forcing stra-p 11' are disposed atright an- Chains, cables glesand extended belowthe lower edge of the beam. Additional netal plates 31 are secured to thelower edge of the beam at its ends and have angularly disposed extremities-32'which are engaged with the ends of the strap 11'. These engaged end portions of the'inetal strap and the plates 31 are provided 'with openings to receive the hooks on the ends of the chains.

From the foregoing description taken in connection with the accompanying drawings, theconstrnction, manner of operation and several advantages of my invention will be app'arent. By mounting the operating Wheel 18 centrally upon the drnm or windlass, the device may' be operated with aminimnm of manual labor, as the objects suspended from the outer endsof the *respective pairs of beams substantially balance each other. The invention is also highly serviceable for expeditiously emptying wagons containing corn or other farm prodncts and storing suchproducts in the corn crib or silo.

The apparatus as a whole is comparativcly simple in its construction and' may be produced at small manufacturing cost.

While I have described andshown the preferred arrangement and construction of the several elements employed, it will be understood that the invention is susccptible of considerable modification in the p'oportions and materials employed in its construction and I therefore reserve the privilege of resorting to all such legitimate changes in these respectsas will be fairly embodied within the spiritand scope of ny invention as claimed, without changing any essential feature of its mechanical operation.

I claim:
